SPECIFICATION forming part of Letters .ippiicauon'ned Apri115,19o1.

T all wltont it may concern:

Beit known that LISA'I'E'FRCHETTE, a subject of the King of Greatlritain, residing at Montreal, in the Province of Quebec and Dominion of Canada, have invented new and useful Improvements in Horn-Rotating Meehan; ism, of which the following is a specification.

This invention relates to mechanism for rotating the horn of boot and shoe peggin g and nailing machines. It is well known to those skilled in the art that in machines of this class when the boot or shoe is being nailed or pegged it is inconvenient for the operator to rotate the horn by hand whennailing or pegging around the toe and around theheel of the boot.

It is the object of this invention to provide a machine in which the operator can at all times hold the shoe with both hands and the rotation of the horn or partial rotation of the horn be accomplished by means of mechanism thrown into operation by the knee ory foot, as may be desired, said rotation of the horn being necessary in nailing around the toe and heel of the boot.

In the following speciiication and in the drawings I have described and illustrated my invention as applied to two forms of peggingmachines.

In Figures 1 to 6, inclusive, of the drawings l have illustrated my improved horn-rotating mechanism as applied to a peggingmachine substantially like that for whichI have obtained Letters Patent of the United' States No. 647,599, in which the horn has a rocking motion and the mechanism by which the horn is rotated is supported upon a stationaryT bracket fast to the column ofy the machine.

In Figs. 7 and 8 I have illustrated my hornrotating mechanism as applied to a peggingmachine in which the horn is arranged to rotate in a ixedbracket upon the column of the machine and the mechanism by which it is rotated is supported upon a lever to which a rocking motion is imparted, as-hereinafter described. l

The invention consists in the combination of mechanisms hereinbefore set forth and means for throwing the mechanism for imparting intermittent rotary motion to the horn out of connection with said horn.

Patent No. 701,193, dated May 27, 1902. seria No. 55,900. (roman.) l

The invention still further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Fig. 1 is a front elevation of a pegging-machine with my improved horn-rotating mechanism attached thereto. Fig. 2 is a left-hand side elevation of Fig.l l. Fig. 3 is a rear elevation in detail of the horn-rocking mechanism. Fig. 4: is a horizontal section taken on line A A, Fig. 2. Fig. 5 isa detail horizontal section of the 'horn-rotating mechanism, taken on line B B Fig. 6 is a side elevation of the of Fig. 1. horn-rotating mechanism, taken from the right of Fig. 1. Fig. 7 is a partial righthand side elevation of a pegging or nailing machine in which the horn is arranged to r0- iate in a bracket fast to the column of said machine. Fig. 8 is a detail enlarged horizontal section taken on line C C, Fig. 7.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, Figs. l to 6, inclusive, is the head,2l the column, and 22 the base, of a pegging-machine similar in construction tothe pegging-machine for which I have 0btained Letters Patent of the United States No. 6a7,599. 23 is the horn, arranged to rotate in a bearing 24:, formed in the rocking frame'25, said rocking frame having a cylindrical shaft 26 cast in one piece therewith and arranged to rock in bearings 27 in the column 21. A rocking motion is imparted to said rocking frame and to the horn 23, thus imparting alateral motion to the tip of the horn, by a-lever 2S, fast to the shaft 26, to which lever a rocking motion is imparted by a cam29, which engages a cam-roll 30 upon the lever 28. The lower end of the horn 23 has a ball 3l formed thereon, pivotally connected by a link 32 to the treadle 33. The treadle 33 is pivoted at 34 to thecolumn 2l and has a counterweight 35 fast thereto, which keeps the horn normally when there is no shoe thereon in an elevated position, with the shoulder 36, formed upon said horn, resting against the lower endof the bearing 24 in the rocking frame 25. The mechanism hereinbefore described is substantially the same as that shown and described `in the patent hereinbeforc mentioned.

The horn IOG vratchet-teeth 37 upon the horn 23.

23 has ratchet-teeth 37 cut upon the vertical part -thereof, located beneath the rocking frame 25 immediately above the ball 31. A bracket 38, fast to the column 21, has a kneelever 39, pivoted upon a stud 40, fast to an ear 41 upon said bracket. Said knee-lever has a short arm 42 thereon, connected by a spring 43 to a pin 44, fast to said bracket. Two paWl-levers 45v 46 are pivoted at 47 48, respectively, to the bracket 38. Said pawllevers are connected together by a spiral spring 49, which tends to draw the serrated ends of said pawl-levers toward each other and into contact with the ratchet-teeth 37. The pawl-lever 45 engages the knee-lever 39 and is forced by said knee-lever against the two-armed dog 50, pivoted at 51 to the bracket 38. The arm 52 upon the'dog 50 engages and partly encircles one end of the pawl-lever 46. It will be noted that the serrated ends of the pawl-levers 45 and 46 are arranged to engage the ratchet-teeth 37 upon opposite sides of a median line D D, Fig. 5.

The operation of the mechanism for rotating thel horn (illustrated in Figs. 1 to 6) is as follows: The horn-rotating mechanism normally stands in the position shown in Figs. 5 and 6, and the horn 23 has a constant rocking motion imparted thereto by the mechanism hereinbefore described, thus imparting a lateral'motion to the tip of said horn; but it does not rotate in the bearing 24 until the pawlelevers 45 and 46vare thrown into engagement w'ith'the ratchet-teeth 37, which is done by the operator pressing his knee against the knee-piece 53 upon the forward end of the knee-lever 39, forcing the said knee-lever in the direction of the arrow, Fig. 6, overcoming the resistance of the spring 43 and carrying said knee lever away from the paWl-lever 45, thus releasing said pawl-leyer, whereupon the spring 49 draws the serrated ends of the pawl-levers 45 and 46 to-V wardfeach other and into contact with the The horn 23 is rocked, as hereinbefore described, to a'slight extent in the direction of the arrow, Fig. 5, and in the opposite direction thereto constantly, thus imparting a lateral motion to the tip of the horn. It will therefore be seen'that as soon as the serrated-ends of the pawl-levers 45 and 46 come in contact with the ratchet-teeth 37 this rocking motion, which in effect is equivalent to a reciprocating motion, willcause said horn to be rotated as long as the serrated'ends of said pawl-levers are held in contact with said ratchet-teeth. W'hen the horn has been rotated a half-turn, more or less, as may be desired, the operator releases the knee-lever 39, which is immediately rocked upon its pivot 40 by the spring 43 and engages the Ypawl-lever 45, throwing it out of contact with the ratchet-teeth 37 and through the dog also throws the pawl-lever 46 outof contact with said ratchet-teeth, overcoming the resistance of the spring 49, connecting said pawl-levers, in order to do so. The horn will now remain stationary so far as rotary movement is concerned until the operator desires to again impart a rotary movement thereto by operating the knee-lever 39, as hereinbefore described.

ln certain machines for pegging and for nailing boots and shoes the horn has no lateral motion, and in machines of this class the rotation of the horn maybe accomplished by substantially the same arrangement of kneelever and paWl-levers as that hereinbefore described by mounting said levers upon a rocking lever which moves said pawl-levers laterally with relation to the stationary horn, and thus supplies a motion Which is equivalent to a lateral movement of the horn itself.

InFigs. 7 and 8 l have illustrated the hornrotating mechanism-viz., the paWl-levers 45 and 46, spiral spring 49, dog 50, and knee-` lever 39--mounted upon ahorizontallever 54, pivoted upon a stud 55, fast to a bracket 56, said bracket being fastened to the column 57 of the machine. The horn 23, Figs. 7 and 8, turns in a bearing 59 in the-fixed bracket 60 upon Ithe column 57. The lever 54 is forked at 61 to engage an eccentric disk 62, fast to a vertical shaft 63. The shaft 63 rocks in bearings 64 64, formed in brackets 65 65, fast to the column 57. The rocker-arm 66, fast to theupper end of the shaft 63, has a cam-roll 67 jou rnaledthereon which engages a cylinder-cam 68, fast to the driving-shaft 69 of the machine. The operation of this mechanism is substan tially the same as that hereinbefore described, in which the horn had a lateral movement, the operation of the knee-lever being exactly the same as hereinbefore described and the operation of the pawl-'levers being the same, with the exception that Whereas in the mechanism hereinbefore described the horn had a lateral movement, caused by its rocking motion, the form of mechanism shown in Figs. 7 and 8 has a stationary horn, and the pawllevers are given a lateral motion by means of the lever 54, which is rocked upon its pivot by the rocking eccentric 62 through the rocker-shaft 63, to which a rocking motion is imparted by the rocker-arm 66, said rockerarm being rocked by the cam 68.

It is evident that the horn may be given a reciprocatory movement by sliding the same laterally, and the same pawl mechanism lwould rotate said horn when said pawls were released to engage ratchet-teeth thereon by means of the knee-lever, as hereinbefore described. Different forms and arrangements `of mechanism may be used to intermittentlryi rotate the horn, combined with mechanism for lraising and lowering said horn, Without de- `hereinbefore set forth without departing from '1 the spirit of my invention.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-

l. In a machine for pegging boots and shoes, a horn, a bearing Jtherefor, means to slide said horn longitudinally in said bearing, mechanism for imparting an intermittent rotary motion to said horn, and means for throwing said mechanism into and out of connection with said horn.

2. In a machine for pegging boots and shoes, a horn, a rocking frame in which said horn is arranged to slide longitudinally, a rock-shaft fast to said rocking frame, mechanism for rocking said shaft, and mechanism for imparting an intermittent rotary motion to said horn.

3. In a pegging-machine, ahorn, a rocking frame in which said horn is arranged to swivel, a rock-shaft fastto said rocking frame, mechanism for rocking said shaft, and mechanism for imparting an intermittent rotary motion to said horn.

4.-. In a pegging-machine, a horn, a rocking frame in which said horn is arranged to slide longitudinally and to swivel thereon, a rockshaft fast to said rocking frame, mechanism for rocking said shaft, and mechanism for imparting an intermittent rotary motion to said horn.
